The Bronx man who was riding a dirt bike when a police cruiser plowed into him last August, killing his friend, was found guilty yesterday of reckless driving and fined $80.

Adalberto Gonzalez, 26, originally faced the more serious charges of reckless endangerment and resisting arrest. But those were dropped after a video of the crash that killed his pal Eddie Fernandez, 28, in Hunts Point was made public in March.

Gonzalez decided to fight the remaining, minor charges of operating a motorcycle without a license and reckless driving.

The video shows cops first knocking him off a stationary dirt bike before he runs and hops on the back of his pal’s bike, which was then rammed from behind by the police cruiser.

Bronx Criminal Court Judge Robert Seewald fined him because the video shows him riding on the sidewalk at a slow rate of speed.
